Answer:
f = -5
Step-by-step explanation:
If 2x – 1 is a factor of 16x4 + 24x3 + 2x + f, find f.
If 2x - 1 = 16x⁴ + 24x³ + 2x + f, find f.
2x - 1 = 0
2x = 1
x = 1/2
Hence
f(1/2) = 16(1/2)⁴ + 24(1/2)³ + 2(1/2) + f
= 16(1/16) + 24(1/8) + 1 + f
= 1 + 3 + 1 + f
= 5+ f
f = -5
16x + 9 = 9y-2x Add 2x to both sides
18x + 9 = 9y Divide both sides by 9
2x + 1 = y Switch the sides to make it easier to read
y = 2x + 1
7/19 are the fraction of men's shoes
explanation + example:
Use the total number as the denominator: 6 + 8 = 14
Use each of the ratio terms as the numerator in a fraction:
6 becomes 6/14
8 becomes 8/14
Reduce each fraction to lowest terms:
6/14 simplifies to 3/7
8/14 simplifies to 4/7
The part-to-part ratio 6 : 8 converts into the fractions:
6/14 = 3/7
8/14 = 4/7
Answer:
There are 1084 pupils in that school.
Step-by-step explanation:
If there are 542 girls and boys then you would have to double 542 to get the total number of people. So, there are 1084 people in that school.
Hope this helps!
